Manifest Rune/Capture the Flag no longer DNR you. Blocks suicides in CTF areas (#78957)

## About The Pull Request

You can return to your old body after playing CTF or being summoned as a
manifest rune cult ghost. This is done by slapping the temporary_body
component onto cult rune summons and CTF bodies. This also extends to
Medisim Shuttle knights.

This also blocks suicides from being performed in CTF areas. Ghosting
and "manually" suiciding is, of course, still an option.
## Why It's Good For The Game

There's no reason these two cases should lock you out of being revived.
They both also dust bodies on death or after their job is done, making
them a perfect fit for this component.

Blocking suicides ensures that all bodies are properly "cleaned up" by
the death dusting process. Gun suicides, for instance, would remove the
brain from the body and bypass cleanup. This not only prevents the user
from being returned to their old body, but likely has other unforeseen
problems that leaving a body behind might cause.
